Application filed July 22, 1915. Serial No. 41,277.

To all whom it may concern: Be it known that I, ALFRED J. STECKER, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Vacuum-Cleaner Dust-Bags and Holders Therefor, of which the following is a specification, reference being had therein to the accompanyin drawings. 4

The invention relates to vacuum cleaners of that type having a movable motor and fan casing to which the suction tool is attached, and a dust bag carried by said casing. It is usual to support the bag by the handle which operates the machine, and to provide for relative movement a yieldable.

support for the upper end of the bag is provided. When, however, the bag is filled with dust the weight is so increased that frequently the spring support is overstressed and permanently elongated. The dust bag must be provided with means of attachment to -the delivery end of the fan, and it is desirable to provide a construction in which the dust may be quickly removed when necessary. With my improved construction l have provided means for yieldably supporting the bag which cannot be overstressed by any load. I have further provided an improved construction of inlet for the dust which prevents falling out when the fan is not in operation; and further a construction that provides for the eas removal of the dust from the bag.

Til the drawings:

Figure 1 is a perspective view of my improved dust bag and support as applied to vacuum cleaners;

Fig. 2 is a longitudinal sectlon through the yieldable support for the bag;

Fig. l is a section on line yy; and

the attachment nipple for the bag, showing the means for preventing the falling out of the dust when the fan is not in operation.

A is the motor and fan casing, of any suitable construction, B is the suction tool, C is the operating handle and D is the outlet nipple on the casing to which the dust bag is attached. For supporting the bag I have provided a spring hanger E, which at its lower end is attached at F to the upper end of the bag, while at its upper end it is provided with a loop G for engaging a hook H on the handle. To prevent overstressing and permanent elongation of the spring by the load of dust I place within the helix links I which permit a predetermined elongation and then form unyielding supports for the load. As shown, this linkage is formed by wire loops 1 and I at the upper and lower ends, and a connecting link l which is bent around the loop at I so as to be longitudinally slidable thereon.

The dust bag J is formed of any suitable fabric, and is provided at its lower end with a tube K for telescopically engaging the nipple L on the fan casing. The tube K is preferably formed of metal to permanently retain its shape, and extends for a short distance only into the bag. From this point a fabric tube M extends farther up in the bag, and is supported preferably by stitching in at the side seam of the bag, as indicated at N Fig. 3. With this construction, when the fan is in operation the pressure of the ingoing air will expand the tube M tit tih

so as to deliver the dust from the openupper end thereof into the bag, but whenever the air current ceases this fabric tube will collapse and form a trap for preventing tubular clip P is adapted to be slid over said selvage edge to form a closure. The tube K is attached to the nipple by any suitable means, such as the bell Q having spring links R adapted to embrace a bend in the nipple and having a point S engaging a notch therein.

In use, the empty bag when first attached is as shown in Fig. 1, and the dust which is delivered by the fan will pass upward through the tubes K and M into the bag. As the weight increases the spring hanger E will elongate until the limit of elongation of the linkage I is reached, after which additional load will produce no further deflection. When the bag is full it may be quickly fall out.

detached from the nipple L, and on account of the collapsible tube M the bag may be carried without reversing to the place for emptying the'dust. The tubular clip P may then be Withdrawn, which will open the mouth of thebag and permit the dust to By reason of the fact that the fabric tube M is stitched to the edge of the bag itcannot fall down or assume any position where an obstruction is formed to the free movement of the air.

What I claim as my invention is 1. A dust bag for vacuum cleaners, comprising the bag proper having a seamed edge, and a collapsible fabric tube forming an inlet for the dust-laden air, having one vedge stitched into said seam.

2. A dust bag for vacuum cleaners, comprising the bag proper having an inlet in its lower portion at one side of the bag and having an outlet occupying the remaining lower end of the bag, and a closure for said outlet extending substantially transverse to said inlet.

In testimon whereof I aflix my signature in presence 0 two witnesses.

I ALFRED J. STECKER.
